WebPageTest 2.17

WebPageTest 2.17 is now available: https://github.com/WPO-Foundation/webpagetest/releases/tag/WebPageTest-2.17

Most of the improvements are around mobile testing and supporting newer releases of Chrome and Firefox.

Hi, I have a WPT Server instance running on Amazon (eu-west-1 : ami-9978f6ee). According to the documentation the Server should automatically update? Mine has not automatically updated to 2.17 (I checked here http://<server_ip_amazon>/install/).
Just wondering if I need to recreate the Server instance to get 2.17? or if there is some config I am missing to autoupdate.
Best Regards
